Question

All of these alkanes, except cyclohexane, have the same chemical formula. Why, then, are these three different compounds?

Answer 1

Because these three have different arrangements of
`-CH_(3)`

Step-by-step explanation:

All of these alkanes:
`C_(5) H_(12)` Pentane, Isopentane, and Neopentane despite being homologous have the same chemical formula and their bonding rearranged, with branches of
`-CH_(3)` differently placed what gives them different physical and chemical properties such as melting and boiling points different.
